            EXPERT: Instructs the FieldCache to forcibly expunge all entries

            test methods as a way to ensure a known base state of the Cache 
            (with out needing to rely on GC to free WeakReferences).  
            It should not be relied on for "Cache maintenance" in general

            a choice of "category" labels picked by the end user. As a filter, this is much faster than the

            box of the given Shape is used to create {@link NumericRangeQuery}s to efficiently
            find Points within the Shape.
            
            Due to the simple use of numeric fields, this Strategy provides support for sorting by
